Tpy6a [65]
1.06(12.25 + x) = 19.08
12.25 + x = 19.08/1.06 = 18
x = 18 - 12.25 = 5.75

Therefore, the cost of the cat food is $5.75

an architect wants to build three similar triangles such that the ratio of the middle triangle. The smallest one has side length
vampirchik [111]

Answer:  15

<u>Step-by-step explanation:</u>

small:     5     12      13

middle:  __   36     39

large:    45   108    117

Notice that to get from the small to the large, multiplied by 9

5(9) = 45    12(9) = 108    13(9) = 117

That is because the sides are proportional \dfrac{5}{45}=\dfrac{12}{108}=\dfrac{13}{117}\rightarrow\dfrac{1}{9}

To get from small to middle, multiply by 3  

5(3) = 15     12(3) = 36    13(3) = 39

To solve it using proportions:

\dfrac{5}{x}=\dfrac{12}{36}\\\\\\\text{Cross Multiply and solve for x:}\\5(36)=12x\\\\\dfrac{5(36)}{12}=x\\\\5(3)=x\\\\\large\boxed{15}=x

If f(x)=3x+2and g(x)=x^2-9 find (f-g)(x)
mel-nik [20]

Step-by-step explanation:

If f(x)=3x+2and g(x)=x^2-9

find (f-g)(x)

f(x)- g(x) = [3x + 2] - [x^2 - 9]

= -x^2 + 3x + 11
